IMPROVEMENT IN GRAIN-DRIERS.

Specification forming part of Letters Patent No. 181,760, dated August29, 1876; application tiled May 4, '1876.

To all whom it may concern Be it known that we, JOHN WILsoN YOUNG andEBENEZEE VINGING WHITE, of La Grosse, county ofIla Crosse, and State ofWisconsin, have invented an Improvement in Grain- Driers.

The following description, taken in connection with the accompanyingplate of drawings, hereinafter referred to, forms a full and exactspecification, wherein are set forth the nature and principles of theinvention, by which the same may be distinguished from others of asimilar class, together with such parts thereof as are claimed as new,and are desired to be secured by Letters Patent of the United States.

Our invention relates to that class of devices which are made use of fordrying grain 5 and the nature thereof consists in certain improvementsin the construction of the same, hereinafter shown and described.

In the accompanying plate of drawings, in which corresponding parts aredesignated by the same letters, Figure l is a side elevation of theexterior of the apparatus. Fig.2 is a vertical section. Fig. 3 is anelevation, partially in section, illustrating the arrangement of thepipes.

In said drawings, a designates a case of rectangular form, having in theinterior there.- of a zigzag spout, b, arranged between, and by meansof, the zigzag plates of metal c.

The grain is admitted to the said spout through the hopper d, and passesout through the lower end thereof.

Between the casings of said spout are arranged a series of pipes ortubes, passing across the inclined sides of said spout, into which`steam or superheated air is admitted. In the upper series of tubes aremade perforations, for the purpose of allowing the steam-to pass outamong the grain when required. When steam is not required it is shut oifrom the pipes c by means ofthe valve g, and, by opening Valve k, thesteam or hot air passes through the pipes m, and the apparatus becomessimply a grain 0r middlings drier.

Having thus described our invention, we claim and desire to secure byLetters Patent of the United States- The apparatus for heating graindescribed, consisting of the case A, zigzag spout b, pipes e and m, andvalves g, h, and k, as and for the purpose described.

In testimony that We claim the .foregoing we have hereunto set our handsthis 14th day of February, 1876.
